Edward Wang bf61bb6b7f Add tests for #12470 and #14285
The #14869 removed `TraitStore` from `ty_trait` and represented trait
reference as regular `ty_rptr`. An old bug of the missing constraint
upon lifetime parameter of trait reference then is fixed as a side
effect. Adds tests for affected bugs and closes them.

Closes #12470.
Closes #14285.
